Hello

There is an error when starting, what could be the problem?

path_optimizer.py:241: VisibleDeprecationWarning: Creating an ndarray from ragged nested sequences (which is a list-or-tuple of lists-or-tuples-or ndarrays with different lengths or shapes) is deprecated. If you meant to do this, you must specify 'dtype=object' when creating the ndarray.

you should use a 0 index .
self.commission_matrix[np.meshgrid(indexes, indexes, indexing='ij', sparse=True)[0]] = self.trading_fee[exc_name]
